We can even help you with root cause analysis if required. We can help you design your Gauge R&R, carry out the study, and interpret results. The intention of a Type 2 study is to quantify the variance that could be expected in production as a result of variation in the inspection process and to highlight areas for improvement, such as fixturing, operator training, the inspection program, or even the hardware. In a good measurement system, there should be minimal variance between the operators running the process. This typically involves multiple operators inspecting multiple parts and then performing a statistical analysis on the results. Type 2 Gauge (reproducibility) StudyДЄ Type 2 gage study is used to determine the reproducibility of a measurement system.

For a manual inspection process the number of runs is normally significantly higher, and could be up to 50 runs. For automated processes, such as CMM inspection, this may be as low as 3 or 5 runs due to the inherent repeatability of automated processes.

In this type of study the part normally remains in situ while repeat measurements are made. It involves repeated measurements of one part, on one instrument, by one operator to establish the baseline repeatability of the inspection process. Type 1 Gauge (repeatability) StudyДЄ Type 1 gage study is normally used to determine the baseline repeatability of a measurement system. These requirements typically specify the actual required number of measurements and operators to be used.

Additional requirements may be stipulated by OEMs such as Rolls Royce, GE or P&W. In the Aero Engine supply chain, the standard AS13003 defines the minimum requirements for an MSA, including the minimum requirements for a Gauge R&R. This typically involves repeat measurement of multiple parts by multiple operators under controlled conditions using the inspection process to experimentally determine the systemвЂ™s capabilities. Gauge R&R is the most common Measurement System Analysis (MSA) method used to practically determine the measurement uncertainty of equipment and inspection processes.ДЄ Gauge Repeatability and Reproducibility Study, commonly known as Gage R&R or GR&R, is a Measurement System Analysis (MSA) tool used in metrology and the inspection industry to determine the equipment variance (repeatability) and process variance (reproducibility).
